The study of the diboson production characteristics with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at √s up to 8 TeV allows to measure the behaviour of the electroweak interactions in an unexplored energy range. This measurement allows to test the Standard Model theory and to search for new Physics by probing possible anomalous couplings at the gauge-boson vertices. This studies are also important because the Standard Model W+W− and ZZ productions are irreducible backgrounds for searches of the Higgs boson in the diboson decay channels.
The measurements of diboson production in ATLAS are presented for different electroweak diboson channels: ZZ, WZ, WW, Wγ and Zγ. Anomalous triple-gauge coupling limits that are obtained from these measurements are also presented.
